shotgun magazine spring fatigue

I have a Mossberg 500 12ga. Will the magazine spring become fatigued if left fully loaded for extended periods of time? Is "downloading" by one enough to take care of it? Is replacing the spring on a schedual worthwhile or a waste of money? Thanks

Most modern springs are quite resilient to spring fatigue, and repeated unloading and loading are more destructive in general than prolonged periods in a compressed or relaxed state. I wouldn't worry about it.

I have had a Moss500 for use as a HD weapon for 18 years now. It is the 8 shot pistol grip model.Shortly after purchase I changed the grip and forearm to the Pachmeyer Vendicator series. It has the same mag spring in it as when i bought it.

I always keep 3 in the mag(3") with chamber empty,hammer cocked and safety on. The only time that I download this weapon is for routine maint. and if we go away on a trip.

No problem with the spring whatsoever. I can put only one round in the mag and it will feed it without a problem.---------
